chose 4 to enable extra software repositories and create a preferences file reducing the liklihood of updating files from the wrong repository.

Then, in a terminal window, sudo apt-get install gramps to install the Gramps 2.2.3-1 package. This is not the latest version but it will install the all necessary support software along with Gramps. I did it from a terminal because I couldn't access the OK button in Synaptic's pop-up window.

Use SublimePorte's Launch Tools to add a Gramps lanucher to the simple interface tab of your choice. The path to the executable is: /usr/bin/gramps.

If you would like to run the latest stable Gramps download gramps_2.2.10-1_all.deb package from http://packages.debian.org/lenny/gramps. Navigate to the downloaded file, right click it and chose Install DEB file. This will update the version that you previously installed. This WILL NOT substitute for apt-get's package installation.
